Title: Cover return prevention mechanism
Inventor: OSADA KAZUYA
IPC: E05C17/46
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent a cover of a case from closing due to spring back or by its own weight when the cover is opened, and to make it possible to close the cover without manual unlocking operation when the cover is to be closed. SOLUTION: One end of a hinge 8 is secured to a cover while its other end is connected with projection-recess relationship to a support port 2 attached to a case 9. The hinge 8 is fold upward with a torsion spring 6 through an arm 7. As the cover is opened, the hinge 8 rotates about a pivot section 3. When the cover reaches a specified opening position, a bent portion 11 enters a corner portion 10 to prevent the cover tram closing. When the cover is closed, the bent portion 11 is sprung back in the direction opposite the opening direction by means of the hinge 8 so that the hinge 8 may move in the opposite direction.

Title: Deodorizing chemical and deodorizing method for aldehides-containing gas
Inventor: OBAYASHI MASATO
IPC: B01D53/18
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To enable highly efficient deodorization treatment by making properties of an aqueous solution of a polyhydric alcohol and sodium hydrogensulfite meet specified conditions when a gas containing aldehides is treated by a filling column chemical cleaning method. SOLUTION: When aldehides are removed from a gas containing the aldehides and deodorization is carried out in a filling column chemical cleaning column, pH of an aqueous solution having a hydrogensulfite concentration of 0.1-10 wt.% is controlled at 0.6-8.0 as a chemical to be used and a chemical solution having a polyhydric alcohol concentration of 0.01-1 wt.% adjusted by addition is used. A sulfite ion (SO3 ion) is highly unstable and can be oxidized by oxygen in a gas and changed into an sulfate ion (SO4 ion) and because the sulfate ion does not cause addition reaction, the sulfite ion is necessary to be prevented from being oxidized. Therefore, glycerol and its derivatives and polyhydric alcohol such as ethylene glycol and its derivatives are added as required.

Title: Treating method for silicon substrate
Inventor: SUZUKI YOSHIAKI
IPC: H01L21/322
Filed: 1985-07-18
Abstract: PURPOSE:To eliminate a low temperature heat treatment to grow an inner defective nucleus by contracting the nucleus to form a nondefective layer on the surface of a silicon substrate, thereby extremely shortening a high temperature heat treatment. CONSTITUTION:A silicon substrate 3 on which oxygen 1 and inner defective nucleus 2 are uniformly distributed is annealed with a lasher lamp having 4X10<4>W/cm<2> of emitting power and 0.5sec of emitting time such as Xe lamp. Then, an inner defective nucleus 2 distributed on the substrate which becomes 1,050 deg.C or higher is contracted or erased, and becomes 1,050 deg.C or lower. The initial state is held in the substrate, but oxygen distribution does not alter since a heating time is very short. When the thus treated substrate 3 is applied to a device process, the surface of the substrate becomes nondefect layer 4 and the interior of the substrate becomes a crystal defect 5 to form a crystal defect layer 6.
